Effect of Anti-gravity Treadmill Training After Total Hip Arthroplasty

Background/Objectives: Total hip arthroplasty is one of the most common orthopedic procedures. When the surgery is successful and followed by high-quality physiotherapy, patients' quality of life usually improves and they return to their daily activities more qui-ckly.. Rehabilitation methods and medical devices are constantly evolving, to accelerate functional improvement. The aim of the study is to investigate the impact of the antigra-vity treadmill on the functional outcomes after total hip arthroplasty. Methods: A single centre, randomised, controlled, open label trial was conduct in Hospital for Medical Re-habilitation of the Heart and Lung Diseases and Rheumatism Thalassotherapia Opatija. 34 subjects were randomly divided into two groups: experimental (18) and control (16). The outcome measures included strength of the abductor muscles, range of motion, visual analogue scale, and Timed Up and Go test and 40-meter Fast Paced Walk test.

Treatment and study plan

antigravity treadmill (ALTERG VIA, Lifeward CA, Inc., Milmont Drive, Fremont, CA, U-SA)

Device

Antigravity treadmill training in the experimental group (EG) involved walking in a straight line at a self-selected, com-fortable pace-without running, shortness of breath, or pain. The treadmill's chamber was set to reduce the participant's effective body weight to 20% of their actual body weight (slight unloading was applied to reduce the need for handrail support and to prevent the use of compensatory mechanisms).

Primary outcomes

  1. hip abductor muscle strength

    Time frame: From enrollment to the end of treatment was 3 weeks.

    The effects of the antigravity treadmill on hip abductor muscle strength was the primary outcome.
